When to use remote events and remote functions?

Use RemoteEvents and RemoteFunctions when you want to change something on the server from the client or change something on the client from the server. You'd need to do this because with Filtering enabled, you are unable to edit the server. To set up RemoteEvents, you'd have to have a script on your server. After that, put a LocalScript in StarterGui. Then, you'd have to put a remote somewhere (perferably ReplicatedStorage). Now let's say you wanted to anchor your torso from the client. To do this, you'd have to type this into the script on the server: remote.OnServerEvent:connect(function(sender, victim) workspace[victim].Torso.Anchored = true end This requires two parameters. The first is automatically set. I put it as 'sender' but it is who is firing the event. The next is the victim that will have its torso anchored. Now that we've done that, let's move into our local script in StarterGui. You now need to fire the event, so to do this we'll do FireServer. An example of that, which would anchor the players torso in our case, would be remote:FireServer(game.Players.LocalPlayer.Name) You might notice, the function had two parameters. Well like I said, the first is automatically set, and would be your LocalPlayer.

Finally, test the game.

Sorry if this wasn't the best it could be, I'm on my phone right now and it's hard to type (because I just cracked my screen super badly)
